' INVENTQR JOSEPH f/orrmA/v WM. 6 c ATTORNEYS Patented June 13, 1933 L 1 UNITED. STATES- PATENT OFFICE JOSEPH C. HOFFMAN, OF YONKERS, NEW YORK, ASSIGNOR TO J. C. HOFFMAN, INC., OF-

NEW YORK, N Y., A CORPORATION OF NEW YORK CONTAINER Application filed August 7, 1931. Serial No. 555,703. I

The invention relates to containers and moreparticularly to that type thereof in which the containers are made of pasteboard or similar material in cylindrical form for containing dry materials such as powders,

fects of atmospheric or other conditions.

Other more specific objects will appear from the description hereinafter and the features of novelty will be pointed out in the claims.

In the accompanying drawings, which 11- lustrate sex eral examples of the invention a without defining its limits, Fig. 1 is a central longitudinal section of a container with the novel closure combined therewith; Fig. 2 is a plan view showing the closure of Fig, 1 which serves as a removable cover; Fig. 3 is an elevation of a container, partly in section, showing another form of the novel cover; Fig. 4 is an inverted plan view of the cover of Fig. 3; Fig. 5 is a fragmentary view of another arrangement of the closure; Figs. 6, 'Z and 8 are detail sectional views showing additional forms of the novel closure; Fig. 9 is a plan view, with parts broken away, of the closure illustrated in Fig. 7; and Fig. 10 is a detail section of a further arrangement of the novel closure adapted principally for use as a bottom for the container.

' In Figs. 1 and 2 the container is shown of cylindrical form with its body 15 or 15 in the nature of a tube, it being understood that this 1s only an example for purposes of illustration and description, and not intended to define the limits of the field of usefulness of the novel closure.

Referring moreparticularly to Figs. 1 and 2, the body 15 is made of pasteboard or other similar material in any customary manner andis of cylindrical form with its opposite ends open,-prior to the combination of the closure therewith. The lower end of the body 15, generall speaking, is permanently sealed by means 0 a closure which may embody the novel features and constitute a bottom suitably secured in place in said body as by cementing or the like; the opposite or u per end of the body 15 is closed by means 0? the novel closure constructed in the form of a cover capable of being easily removed from and inserted into said body 15 at will.

In the example illustrated in Fig. 1, the removable cover and the bottom are generally of similar construction, and each com prise an outer member comprising a disk, and preferably a flexible disk 16 or 16 respectively, of suitable material, such as cardboard, sheet metal or the like, said disk 16 or 16" customarily being made of cardboard or its equivalent, The disk 16 or 16 constitutes an independent element which is in permanent connection with an independent flange 17 or 17 any suitable means may be utilized for connecting the disks with the flanges, the preferred arran ement being to provide the annular flange 1 or 17 a with a crlmped bead 18 or 18 to form an integral part of each flange and extending over the peripheral edge of t e disk, as illustrated. In the preferred form the overlapping portion of the bead 18 is embedded in the disk 16 so as to lie substantially flush therewith as shown in the drawin s; with this arrangement the external sur ace of the closure is smooth and even and is free from any annular ridge against which dust or dirt mi ht lodge. It will be obvious that the bea 18 of Fig. 1 may be correspondingly combined with the disk 16*,

outer member is fixed against depression con-' sists of an arched section 20 or 20, comprising an integral part of the bottom 19. In both instances, the arched sections 20 and 20 extend into surface engagement with the inner face of the disk 16 and 16 respectively, the arched section 20 being arranged and dimensioned to force the disk 16 to an outwardly flexed position, and to maintain it therein; the arched section 20 on the other hand is so proportioned that the disk 16a is iIpaintained in a flat position, as shown in Jls is clearly shown in Fig. 1, the closures are of the plug type and are dimensioned so that the flanges 17 and 1'? snugly fit into the container 15 at opposite ends thereof with the crimped beads 18 and 18 overlapping and engaging the opposite ends of said container. As previously stated, the bottom closure is preferably permanently secured in the container 15 in any convenient manner,

as by cementing or gluing. The cover, on the other hand, is removably fitted into the container 15 so as to be removable at will to render the interior of said container 15 accessible. In actual practice, it has been found that containers of the type in question, particularly when made of asteboard or the like, are subject to physical changes, such as shrinking resulting from atmospheric changes or other causes, so that the transverse dimensions of the container decrease. In the case of the customary type of cover which slips exteriorl over the end of the container, such shrin age tends to unintentionally loosen the cover whereby the sealing function thereof is rendered insecure and ineflicient. With the present novel type of closure, the aforesaid shrinkage results in clamping the cover more securely in place and results in an improved and more eflicient sealing action therein. The novel construction of the closure permits the combination of the outer member or disk, with the remainder of the closure in an eficient manner, which-results in an attractive and til-(I'Ollgllly eflicient seal; it also enables the disk or' outer member to be constructed of cardboard or other relatively inexpensive material and avoids the possibility that said disk will be unintentionally depressed in the direction of the axis of the closure to spoil the appearance thereof. The arrangement also enables the disk or outer member 16 or 16a to be printed or otherwise provided with adver tising matter in a simple and easy manner prior to its connection with the flange of the closure.

in containers which comprise tubes of relatively heavy cardboard or all tcrial which inherently develop a re large degree of friction on the flange equivalent, it is generally preferable l vide the closure with suitable spacing devices aeiaeea which, in the illustrated example shown in Figs. 3 and 4, are indicated as projections 21.

interva son the inner surface of the crimped bead'18 so as to extend downwardly therefrom into engagement with the end of the rojections 21 are located at spaced stead of providing a bottom closure such as is illustrated in Fig. 1, the container may include a bottom closure 23 of any suitable type for instance, such as indicated in Fig. 3; this bottom closure is also permanently secured in the container in any suitable manner.

To provide a yielding or cushioning connection between the cover closure and the container such as 15, the latter may be provided interiorly at its one end with a cushioning head 23 adapted to engage the flange 17 or equivalent and formed by rolling the material of which the container 15 is made, upon itself, as indicated in Fig. 5. With this arrangement a most eilicient seal is provided between the cover closure and the container.

As shown in Fig. 6, the means whereby the disk or outer member is fixed against axial depression comprises an arched section 20 which lies against the inner surface of the disk 16, and isso arranged as to force said disk 16 into an outwardly flexed position and to maintain it therein. The arched section 20 comprises an integral extension of a sec ond flange 17. located within the first flange 17 and connected therewith by a bend 17. The disk 16 in the form now being described may be connected permanently with the flange 17 by means of a crimped bead 18, as in the forms previously referred to.

In Figs. 7 and 8, the closure includes a bottom section 19 comprising an integral part of the flange 17, and spacing devices ongaging the opposed faces of said bottom section and disk to fix the latter against inward depression. The spacing devices, in the illustrated examples, comprise tubular members 20 dimensioned in the direction of ber 20 and dimensioned to snugly fit within the flange 17, as clearly shown in Fig. 7. The

washer 24: serves to prevent displacement of the tubular member and may be made of cardboard or other suitable material; the

tubular spacing member 20 may likewise be otherwise this form of closure may be the same as the one illustrated in Fig. 1.

While the closures in all of the illustrated examples are shown of circular form to fit containers of corresponding circular shape,

it will be understood that the novel features may be embodied in closures for non-circular containers. In all of its forms, the closure is of simple construction capable of being produced at relatively low cost to provide an eflicient closure for containers arranged to contain dry materials such as powders, crystals, cereals, etc. The closure 1s particularly adapted for use in connection with containers for face powders and the like which in the most common form are referred to as compacts, in which case the arched sections'provide spaces for the accommodation of powder pufls when the closure is in place'on the container.

Various. changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of the invention.
